Are you saying this doesn't work (see image)?

I would try going to Tools | Settings | General | Files & Attachments

and change the "Save files to" and "Always ask me where to save files" settings to something else. Restart Thunderbird and change those setting back to what you prefer. Might reset things.

Same thing has started for me also. All attachments used to save on a folder when it was detached before. Without any changes done, just on updating the Thunderbird software, the attachments now detach and delete from the email, but when I check the same folder there is no file detached and saved there, while the file gets deleted from the email and lost forever.

Have put this on many forums as well as bugs but no respite, please help Mozilla, FIrefox and Thunderbird team.
